| 摘要 |
A backward shifting and accelerating synchronous control system installed in a remote-controlled gasoline engine toy car and controlled by a remote controller to move the toy car backwards and to accelerate the speed. The system includes an accelerator control unit held in position by a torsional spring and turned to control the oil flow rate of the backward steering accelerating oil valve of the engine of the toy car, a swivel arm, the swivel arm having a first end coupled to the forward/backward steering control mechanism of the gasoline engine toy car by a first link and a second end coupled to the accelerator control unit by a second link, and a server controlled by a remote controller to turn the swivel arm, to further shift the forward/backward steering control mechanism to the backward steering mode and drive the accelerator control unit to open the backward steering accelerating oil valve of the engine of the toy car.
